I went on my Lex for a few games today. Once, when my one fighter got swarmed by two, I disengaged after a bit. At the cost of one plane my fighters made a strafe away from the enemies and the two enemy fighters were left flying at where the air battle was initiated for a couple seconds and my fighters got a head start. My slower Corsairs left the faster T8 Shokaku fighters in dust as they fled back home.
Seems handy...that, or my enemy just didn't respond... Does it even work that way by locking the opposing fighters where the battle was going on for a few seconds when disengagement is initiated?
